Doi : stands for Digital Object Identifier.  APA format used DOIs in place of web addresses in citations. 

Why do I need a DOI?  

A unique DOI is assigned to every published journal article, so you can use it as a search.  If you put the DOI in Omnisearch, one of the library databases, or Google Scholar, it should retrieve the article.

1) First, the first page of the article may have a DOI.  A DOI is identified as such on the first page; i.e.,

  DOI: 10.1016/j.anireprosci.2006.12.005   

2) DOIs are often included in database records.  Thus, if you are searching a library database like Academic Search Premier or Research Library, if a DOI is assigned to an article, you will find in the database record for that article.

>3) DOIs may also be found in the bibliography of an article – as authors are now using DOIs as a citation tool.  If you have just the DOI, and want to find the actual article (or at least further citation information), you can use a DOI resolver (see
